The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize ...

The cosmological constant has been a problem in physics since Einstein, but new research may show why it takes the value that ...

The cosmological constant problem, or the vacuum catastrophe is a discrepency in the observed values of the vaccuum energy ...

At the heart of the Big Bang model of cosmic origins is the observation that the universe is expanding, something astronomers have known for nearly a century. And yet, determining just how fast the ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the ...

The universe is approaching the midpoint of its 33-billion-year lifespan, a Cornell physicist calculates with new data from dark-energy observatories. After expanding to its peak size about 11 billion ...

General Relativity continues to provide a robust framework for understanding the interplay between gravitational waves and the cosmological constant. Gravitational waves—ripples in the fabric of ...
